It seems to do some tone shaping somewhat like the Resonance knob but not as dramatic. Rolling it to the left makes it more useful for the bass. Isn't that the rate knob's job? GlennThe rate knob changes how fast the delay time is varying. The manual knob changes the range of the variable delay time. How's that? Need more of a description?Try this: Rate at it's slowest Res at it's max Depth at it's max Then, with manual fully counter-clockwise, pick a note and pluck it over and over again, slowly. Listen to the sweep all the way up, all the way down, and all the way up again. Now, put the manual control fully clockwise and repeat the listening test. It's subtle, but it's definitely there. I can even hear it just from the self generated noise the thing makes with no input signal.

Oh yeah, and to REALLY prove it, pop open the thing and tweak the internal RES pot up a bit, with the right twiddling you should be able to get it to self oscillate, and you'll find the manual control has a significant effect on the tone it produces.

The tremolo effect can be used with the flange at the same time or without the flange and on its own. I found this fantastic as you really get your money's worth with it. It is a very sturdy pedal on top of that. I have had no problems with it and I have had it with well over a year now. This boss pedal is to a high standard and creates no hiss. The Ultra flange option gives you a more intense flange sound which i found very useful. For a more subtle sound the standard one fitted my requirements perfectly. The only disadvantage with the pedal is that it can take a long time to find the right flange sound you want as you have to create it yourself. However for me I found that it added to the diversity of the pedal. I would highly recommend this pedal to someone who wants to make their guitar sound more interesting.

I probably wouldn't recommend running it over with your car, but I also wouldn't bet against it functioning if you'd unfortunately done so. One of the most attractive features that always draws me back to boss is their size. Being a sound junkie I am always experimenting with various arrangements of pedals on my board, and by using boss pedals that are built extremely concise they permit musicians such as my self the ability to fit far more pedals on one board then if i were to use pedals of different makes. In closing Boss Pedals are great sounding, easy to use, superior construction, easy to modify and relatively inexpensive.

I do own many other brands of pedals but when I am in the market for something new to produce some new desired tone required by a particular song or arrangement I always check Boss's lineup first for all the reasons listed previously to see if they have something to accommodate.I'm sure the newer version is no different outside of separate guitar and bass inputs. Maybe 1 and 11 respectively or right in between. That will get you close enough to tweak from there.Once you shut it off it still adds some high frequencies on your signal path. The best use for me would be with a looper true bypass where I can choose how I want my signal at the time. Straight clean, distorted, wha, or flanger. 4 stars only for not being true bypass. But yIt's got all the tone adjustments you need while making it easy to use. And as always, all of Boss's pedals are built like tanks. Mine has taken quite a beating yet still works and sounds like new. Did you miss your activation email ? The problem is that I'm getting no effect sound, just dry signal whether it's on or off. I got some advice on another forum, and did an audio probe test (though my knowledge is limited and I'm very much a learner at this stage). None of the pins on that pass the audio through, but a couple of them mute the whole signal, even the hum. So could it be that one that's causing the trouble. And if so, can I replace that with a CD3102, which I have one of lying around. Also, I get no audio signal from IR9022, but I do get what I think is the clock signal from one of the pins, and it changes speed when turning the rate knob. Is that a good sign. The sound itself doesn't come through that, but does the pulse indicate that that one still works. Any help or advice on what I should do next would be very much appreciated. Cheers! If you can hear audio output at 50khz, you're a better man than I.

The fact that you get clean signal in both effect and bypass mode indicates there is nothing wrong with the supply of power to all the chips. Since you have not made any mention of being unable to switch from effect to bypass or vice versa, that would suggest the issue is most likelt relegated to the FET switching. If you can get a probe in there, check for a change in DC voltage (most likely in the range of only a couple of volts) at the collector of Q10 (where R56 and R61 contact each other). If you get a corresponding change (DC voltage goes up when the LED goes on), then the flip-flop is clearly OK, and the problem lies most likely in the FET itself. You can confirm this by temporarily soldering in a wire link between the output of C20 and R29.Threw it on the scope to calibrate and when done it worked just fine. My suggestion is to probe pin 7 of the MN3207. This is the output pin and if you are getting signal out the chip is fine. You should be able to freeze the LFO sweep by rolling all of the knobs CCW and then listening on pin 7 while turning the manual knob. You should hear a pitch bend. Check the LFO for voltage swing and if you have a way to measure frequency check TP1 for clock frequency. These steps should narrow it down quickly - but if you dont know the history of this pedal start by slowly turning the bias pot. Always good to see you on here Mark. I have truly regressed to the lazy mans approach when trouble shooting ICs. I put my scope probe at pin 1 and go around until I have established input, clock, output etc. When I was observing the MN3207 I made it to pin 7 and saw output and stopped there. So yes, pin 7 OR 8 will show output according to pin out. That is, is this aspect of the pedal working. Is that aspect working.And Mike, well, I turned the BBD bias just a bit, lo and behold, it's a flanger again. I can't believe the amount of head-scratching and messing about for weeks, and that's all it was.

Is the wrong pot value the likely reason for that, or does the BBD need more adjustment. Or both? Or should I just quit before I break it altogether. Thanks again folks. If you have installed 100k, try strapping a 50k resistor (likely 47k) across the two outer pot lugs in parallel to bring the pot value down to 50k. As to the biasing of the BBD, ideally you would use a signal generator and an oscilloscope to find thw optimum setting. Guessing you do not have access to the tools for that you can get close enough for rock and roll with an audio probe and tone generator app on your phone or computer. Run a search for this procedure but it will involve isolating the BBD path output and adjusting for clean headroom.The resonance trim can and should be readjusted after the BBD bias step to properly calibrate the resonance control. Also, my apologies for any typos in my replies as i am on mobile. As part of that, unsolder one end of R28, which mixes clean signal in, so that ALL you hear is delay. If you can listen to the pedal through headphones, even better. As for the Depth pot, 100k should be okay until you can score a suitable replacement. What you might lose is the ability to nudge the sweep upward or downward with a bit of Manual, but nothing worse than that. However, I've got another BF2 and I'm just sitting comparing them now. Should I try tweaking the other trim pots a bit? i.e. Turn the reso trim pot clockwise slightly, and try and match the two pedals by ear.If you have installed 100k, try strapping a 50k resistor (likely 47k) across the two outer pot lugs in parallel to bring the pot value down to 50k. 100k resistor. LED turns red but no effect at all, just dry signal whether it's on or off. I swapped out the MN3207 and MN3102 for new ones, but that didn't help. I checked the switching like Mike Hammer suggested and it seems to work ok. I also bypassed the FET mimicing Q4 being on, but still no effect.

I tried different settings on the bias pot, but it's still not flanging. I noticed that the 5V voltage regulator gets very warm, could that indicate that any of the ICs is broken and draws to much current. The output of the voltage regulator 78L05 is 4,8 V so it seems ok. I suppose I should get an oscilloscope so I can see what's going on. Any other suggestions that could be checked with a multimeter or any circuit that is likely to fail ? Thanks. Thanks for the quick reply That could be a blob of solder or a bit of wire clipping or just some muck. A dead cap is a possibility, but it's not the only one. Check the board visually to make sure you can't see anything causing one track to touch another around the BBD and clock chip. HTH, Tom Sometimes flux on the board can make solder bridges hard to see. It's not absolutely necessary to have a board scrupulously clean of flux, but when you're troubleshooting, being able to see bare board where bare board should be is a nice thing. Sometimes flux on the board can make solder bridges hard to see.So now I want to thank you guys for the help, couldn't have fixed it on my own. Thanks.
